METAL WINDOW-FRAME.

Specification of Letters Patent. Patented Sept. 10, 1912.

Application iiled January 24, 1912. Serial No. .673,161.

Be it known that I, Eno); R. LEONARD, a citizen of the United States andof the State of New Jersey, residing at Woodcll, New Jersey, haveinvented certain new and useful Improvements in Metal -Wlndow- IFrames,of which the followingl is a specication. I

My invention relates to wlndowy frames, of what are known as theboxtype', winch are formed of sheet metal and are provided withhollowsides; and it consists in the particulars hereinafterset forth. In thedrawings, Figure 1 is a vertical view, from th inside, of one side of aWindow frame embodying my invent-ion, the top and bottom being shown insection, and the guide rails bein removed. Fi 2 is a side view of oneofe guiderails; i 3 is a cross sectional 'view of a window ame embodyingmy invention, with upper and` lower sashes in place, and broken away inthe center; and Fig. 4 is a cross sectional view, on an enlarged scale,of one side of the window frame, and of the guide rail de-` tached, thecross stays being emitted.

The same parts are desi ated by the same reference numerals in a thefigures.

The frame is made of,` sheet metal, bent into proper form, with asuitable base 1, and top 2, connected by hollow sides 3, 3, rovidedYwith front stops 4, 4, and stiifened y metal cross stays 5, 5, andhaving vertical openings 6, 6, the edges of which are folded over, asshown at 7 and 8, so as to provide grooves for the rece tion of theflanges 10 and 11 of the gui erails 9, 9.

These guide rails have the stop heads 12, 12, and the parting strips 13,13, formed integral with them;'and they are also provided with holes 14,14 for the passage of the bolts 15, 15, to enter the holes 16, 16, inthe cross stays or braces 5, 5, so as to anchor the guide rails thereto.

In assembling the frame and the sashes. the top sash 17, is first put inposition vagainst the front stops 4, 4, the bottom sash 18 is thenplaced between the guide rails, its edges restmg in the grooves therein;4the lower ends of the guide rails are then placed in position` upon thebase or sill 1, and the tops of the guide rails are pushed into the topof the ame, the bevel 19, of the tops permitting this to be done. Inthis operation the flanges 10 and 11 will respectively enter the grooves7 and 8, so `that when the guide rails, with the-bottom sash betweenthem, have been pushedhome, the openings 6.6 inthe frame will becompletely covered,

and the guide rails may be secured in 'place by the bolts 15; 15,threaded into the cross braces 16, 16. By this construction I secure lawindow frame wherein but two pieces need be detached in order to removeor 1n.

sert the sashes; which is simple, strong and reeproof; and inwhich,vwhenth'e ide rails are removed, both sides of the ame will beopen from the' top to 'the bottom,

'giving direct access thereinto for thel arrangement, adjust-ment orrepair of the balance weights, chains, automatic-.closing liances orother attachments whichmayllie o'cated therein. This latter feature 1s agreat advantage, as it saves time and labor. and, avoids the diicultiesand annoyancesl and the use of s ecial tools which are involved whenworwithin the hollowsidcs of thewindow frame must be done, as is usual,through a small opening extending but .part way up the frame s side.

It isobvious that the form of the interlookin parts of the guide railsand fra'me might varied without de arting from the spirit of 4myinvention, an I do not desire to confine myself to the speciiic forms ofgrooves and flanges shown. But

Having thus described my invention, what I c aim and desire to secure byLetters Patent of the United States'isz- The combination, with a met-alwindowframe, of hollow sides each formed of a.

single piece of sheet metal the vertical edges whereof are separated andare bentto form backwardly opening grooves the forward one lying outsldeof and the other inside of 'the plane of the bottom of the sash' groove,metal cross braces bentto accommo grooved edges,

and means for attaching saidguide rails to said braces. v
